how to fix the air conditioning in my Ford Mustang S650 (2024-Present) blowing hot air

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery before working on electrical components.
• Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Recharge Refrigerant

• Tools Required: Refrigerant gauge set, refrigerant canister, safety glasses, gloves.
• Check the low-pressure side of the AC system using the refrigerant gauge. If low, proceed with recharging.
• Follow the instructions on the refrigerant canister to connect it to the low-pressure port.
• Start the engine and turn on the AC to the maximum setting.
• Slowly add refrigerant until the correct pressure is achieved according to specifications.

3. Inspect and Replace Cabin Air Filter

• Tools Required: Screwdriver or trim removal tool.
• Locate the cabin air filter housing, usually behind the glove compartment.
• Remove the glove compartment to access the filter.
• Take out the old filter and inspect for dirt and debris.
• Replace with a new cabin air filter, ensuring it is oriented correctly for airflow.

4. Check and Replace AC Compressor

• Tools Required: Socket set, torque wrench, AC compressor replacement kit (if necessary).
• Visually inspect the AC compressor for signs of wear or damage.
• If the compressor is not engaging, disconnect the electrical connector and test it with a multimeter for power.
• If faulty, remove the old compressor by loosening the mounting bolts and disconnecting the refrigerant lines.
• Install the new compressor, torque the bolts to manufacturer specifications, and reconnect the refrigerant lines.

5. Inspect and Clean AC Condenser

• Tools Required: Hose with water, soft brush.
• Locate the AC condenser in front of the radiator.
• Inspect for debris or physical damage.
• Use a hose and soft brush to clean the condenser fins carefully, ensuring airflow is not obstructed.
